I've made cabinet door and drawer pulls. They are really easy. I also made a new knob for an antique dresser that lost one of its knobs.I hadn't thought about doorknobs, but I would love to do cabinet door pulls. I actually found a kit a few years ago that could be used for cabinet pulls, but the kits were something like $7 each, and that's a lot of money for a kitchen with ltos of cabinets. I couldn't figure out a way to do it without said kit, so I gave up on doing that for my new house. But I do think it would look super cool and should be do-able!
